Abstract: A method for the production of linoleum 
     A method for the manufacture of a sheet covering (7a) starting from natural oils subjected to oxidation (6) enables the step of seasoning the finished product to be eliminated by virtue of the addition, before the calendering, of cross-linking and accelerating agents which enable the product to be vulcanised rapidly. It is also possible to eliminate the conventional jute fabric by coupling in a calender (5) with a backing sheet (2b) based on a vulcanisable elastomeric material.

Abstract: A semi-flexible double-ridge waveguide comprises a corrugated tube formed into a special dumbbell-shaped cross-­section defined by parameters which are conveniently optimized to realize improved power-handling capability as well as improved attenuation and VSWR factors across extended dominant-­mode operational bandwidths. The dumbbell-shaped cross-section efficiently removes the problems typically associated with the use of conventional rigid waveguide, including difficulty of installation as well as the need for precise alignment of components, by combining flexibility and ease of manufacture, even for long lengths of waveguide, through use of a continuous, uncomplicated and relatively inexpensive process. 
     The dumbbell-shaped cross-section is totally devoid of corners and other abrupt protrusions and is defined by a geometric equation in which specific parameters can be correlatively optimized to improve desired electrical properties of the waveguide. The waveguide is rendered "semi-flexible" by the provision of helical corrugations having a staggered disposition of opposing corrugation crests and troughs, whereby the breakdown air gap and, consequently, the maximum power rating is increased.

Abstract: In a potentiometer for determining the position of a mobile element, in particular the throttle flap in a motor vehicle, a wiper (24), which does not carry current, is arranged towards the maximum position in the movement direction, in addition to the wiper (23). The wiper (24) cleans the surface of the resistor track (21) and the wiper track (22) of the potentiometer beyond the maximum position for the current-carrying wiper (23). In consequence, the critical region between the surface of the potentiometer over which the wiper does not pass, which is subjected to an ageing process, and the surface which is used for measurement, is displaced beyond the maximum point VL. The very high contact resistance occurring in the region of the critical point can thus no longer corrupt the measurement signal. Faulty indications of the control unit of the injection system can thus be prevented. <IMAGE>

Abstract: 2.1 To create trick effects in video recordings, frame buffers or external computers are frequently used. However, these approaches are too complex for consumer electronics. It is therefore the object of the invention to specify a simple arrangement for generating a trick effect. 2.2 This object is achieved by the fact that the digitized image signal is delayed at the time when the colour synchronisation signal occurs. This changes the phase of the colour synchronisation signal by a defined value which results in defined colour changes in the image signal. 2.3 Video devices with digital image signal processing. <IMAGE>

Abstract: To eliminate gyroscope errors in electrically stabilised two-axis gyroscopes in which one pick-off (52, 54) and one torque generator (46, 48) are arranged on each input axis (X, Y) and the output from each pick-off (52, 54) arranged on one input axis is applied to the torque generator (48, 46) arranged on the other input axis, a first measurement is taken at a first direction of rotation of the gyroscope rotor (42). During a second measurement, the direction of rotation of the gyroscope rotor (42) is then reversed and, at the same time, the polarity of the signals of the pick-offs (52, 54) is switched over. From the gyroscope signals obtained during the two measurements, a measurement value is formed.

Abstract: Disclosed is an everting balloon catheter (10) in which the balloon (20) has a waist (94) at the desired eversion point to minimize the size of the distal tip (96) of the catheter during insertion. Preferably, the distal end of the outer body is bevelled and the waist is located just distal and radial to the tip of the outer body (12) when the inner body (14) is fully extended distal to the outer body. Usually, the waist is formed by heat shrinking the balloon during manufacture, thus usually increasing balloon thickness at the waist. 
     Also, in the disclosed invention, the balloon is attached to the outer catheter body via heat fusion. Generally, the outer body and the balloon are both formed of compositions having at least one component in common to promote heat fusion for attachment of the balloon. Preferably that component is polyethylene.

IPC: H01L21/28
Filed: 1991-04-12
Abstract: An insulated gate field-effect transistor or similar semiconductor-insulator-semiconductor structure has an increased time-dependent dielectric failure lifetime due to a reduction in the field across the gate insulator. The electric field in the gate insulator is reduced without degrading device performance by limiting the field only when the gate voltage exceeds its nominal range. The field is limited by lowering the impurity concentration in a polysilicon gate electrode so that the voltage drop across the gate insulator is reduced. In order to avoid degrading the device performance when the device is operating with nominal voltage levels, a fixed charge is imposed at the interface between the gate electrode and the gate insulator, so at a gate voltage of about the supply voltage level the response changes to exhibit less increase in the drop across the gate insulator for higher voltages. Also, the impurity level in the gate electrode may be low enough so that the gate is in deep depletion for transient increases in gate voltage, thereby limiting the drop across the gate insulator.
